stages of formation, Fig. 1G is a perspective view of the knife and Fig. 17 is a perspective view of a guide for the knife.

' In these views, 1, represents the main frame which is here shown as comprising two longitudinal side bars 2, cross bars 3, connecting said side bars, legs 4, and standa-rds rThe standards 5, are supported upon the longitudinal side bars 2, and support the candy feeding mechanism 6, the cutting' mechanism 7, the lubricating mechanism 8, and the candy shaping mechanism 9.

The candy stock is received upon a pan by posts 11. It is `fed by hand from this pan into the feeding mechanism. The feeding mechanism comprises in g'eneral a chute 10a, a hopper 12, and a feeding chamber 13, in which are journaled a plurality of spiral conveyers or worms 14. The chamber 13, is provided within a casing 13a, which is supported upon the standards by ears 13b. The worms are arranged side by side in the feeding chamber 13, and the front end of the feeding chamber is provided with a plurality of spouts 15, containing discharge orifices 15a, which are preferably arranged in alinement with the worms 14. The material is forced out through these orifices in the form of Ibars which are cut olf by the cutting mechanism into small blocks. In the preferred fo-rm, these orifices are round, so that the stock comes out in the shape of a round bar.

If desired, a rotatable paddle 16, may be provided in the chute 10a, to assist in supplying the feeding chamber 13, with the candy stock. The paddle may be geared to the driving mechanism as will appear hereafter'. This paddle may be dispensed with if it is so desired.

The worms 14, have spindles 17, which project out of the rear end of the casing, and said spindles carry pinions 18, which intermesh with each other as clearly indicated in Fig. 4. The end spindles 17', carry spiral gears 19, which mesh with spiral gears 21, secured upon the upper ends of vertically extending' shafts 22. Said shafts 22, are journaled in bearings supported upon the side bars 2, and carry spiral gears 23, upon their lower ends which mesh with spiral gears 24, that are carried by the main drive shaft 25, of the machine. This arrangement provides a very simple form of gearing between the driving shaft and the feed worms.

The main drive shaft extends across the machine and is journaled in bearings secured upon the longitudinal side bars 2. 1t carries upon one end a drive pulley 26, and two gears 27, 28, and upon its other end a gear 29. The gear 29, meshes with a gear 39, journaled upon a stud extending out from the frame and said gear 30, operates the cutting mechanism which will now be described.

A knife carrying bar 31, (see Figs. 10 and 16) is guided to move vertically in standards, 32, secured to the frame of the machine, and to the bar 31, is secured a knife 33, which has a cutting edge upon its lower edge. The knife extends immediately in front of all of the spouts of the feeding chamber and is arranged to be reciprocated vertically and at predetermined intervals so as to cut off blocks of the proper size. The bar 31, is carried by two arms 34, which are mounted upon a cross shaft 35, journaled in brackets 36, secured upon the flanges or ears 13b. One end of each of said arms 34, is preferably forked to embrace studs 36, which extend out from the bar 31, and the other end of one of said arms 34, is secured to a connecting rod 37, which rod carries upon its lower end a roller 38, that rides upon a cam 39. The connecting rod 37, is guided in a post 40, and is raised by the point 41, of the cam 39, once during each revolution of the same. A spring 41a, acts to raise the knife to its upper position. Said cam is connected to the gear wheel 30, so as to revolve therewith and the arrangement of the gearing between the main drive shaft and gear 30, and between the main drive shaft and feed worms 14, is such that the worms will feed out the proper amount of stock to form a block of the right length during each rotation of the gear 30, and the knife will then cut off said block of stock.

Immediately below the discharge orifices 15a, is journaled a feeding roller 42, which is arranged to feed the stock, as it falls from the spouts, to the shaping or molding devices. The roller 42, in its preferred form contains a plurality of circumferentially arranged grooves in its surface, which grooves are arranged in alinement with the discharge orifices and through which the severed blocks of stock fall. A shaping cylinder 43, is journaled in front of the feeding roller 42, and in its preferred form also contains a plurality of circumferentially arranged grooves in its surface, which grooves are in alinement with the grooves in the feeding roller 42, and with the discharge orifices 15a. The roller 42, and cylinder 43, are geared together by gears 44 45, which are mounted upon shafts 46, 47, that eX- tend out from the roller 42 and cylinder 43,

respectively. The shaft 47, has a sprocket wheel 4S, secured upon its outer end which is connected with a sprocket wheel 49, by a sprocket chain 50. rl`he sprocket wheel 49, is mounted upon one end of a shaft 51, which extends across the machine and 'is journaled in bearings secured to the side bars 2, and said slnft 51, and carries upon its opposite end a gear wheel 52, which' meshes with the gear wheel 27, on the main driving shaft 25. The gearing is such that the shaping cylinder 43, is driven quite rapidly, whereas the feeding roller 42, is driven at a somewhat slower rate of speed. A shaping plate 53, is arranged adjacent to the roller 42, and cylinder 43, and contains a number of beads 54, which enter the grooves of the roller 42. The plate 53, has two arc shaped faces 55, 56, the planes of which are struck from the axes of the roller 42, and cylinder 43, respectively, as centers. The contour of the face 55, corresponds with that of the roller 42, and fits against said roller so as to provide a closure whereby the candy stock cannot escape or be carried around by said roller. The face 56, contains circumferentially arranged grooves 57, which are arranged in alinement with the beads 54, and said grooves lie opposite the grooves in the cylinder 43, thus forming channels or passages through which the stock is rolled by the cylinder 43, the effect being that the stock is rolled between the grooved faces of the plate and cylinder until the stock bodies take the form of sphere-s. The configuration of the surfaces of the plate and cylinder may of course be changed to vary the form of the bodies of stock.

The cylinder 43, is made readily removable from its shaft and as shown this is accomplished by making the shaft in two parts 47a, 47h, which are journaled in the standards 5. Each stub shaft projects into the cylinder and has a collar 57a, secured to it, which collar bears against the end of the cylinder. The collar on the stud shaft 47", has a pin 53, which enters an opening in the end wall of the cylinder and couples the cylinder with the shaft.

The shaft 47a, is movable endwise of the cylinder but is held in place by a block 59, which is interposed between the collar 57a, and the standard 5. The block is held in place by any desired means, here shown as a wing nut 60, threaded upon a pin 60', and bearing upon an arm 61, of the block. By unscrewing the wing nut, the block 59, may be removed, the shaft 47a, moved back, and the cylinder 43 withdrawn.

Below the shaping cylinder is supported i a platform 62, over which travels an endless conveyer belt 63, that is arranged to carry the rolled bodies under a flattening cylinder 64, and subsequently carry them toward the end of the platform for removal. The belt 63, is carried by two rollers 65., 66, journaled in bearingsmonnted on the side bars and the roller 66, is intermittently advanced by a pawl and ratchet mechanism 267, 68, which is operated by an eccentric 69, mounted on a shaft 70. The ratchet '68, is fast upon the shaft 7l, which carries the roller 66, and the pawl 67, is carried by an arm 72, which is loosely mounted upon the shaft 71. rlhe arm 72, is connected to the eccentric by a rod 7 8. It is evident that each revolution of the shaft 70, .advances the belt one step. The shaft 70, extends across the machine and carries a gear 74, which meshes with the gear 2S, on the main drive shaft 25.

paper covering 75, is provided for the belt, and the confection's fall upon said covering. The covering` is drawn from' a roll ofV paper carried by a roller journaled in brackets 76. The covering passes between the roller 66, and a weighted roller 77, which arrangement facilitates the moving of the covering along with the belt. The flattening cylinder contains circumferentially arranged grooves in its surface which are somewhat Wider than the grooves in the shaping cylinder, and said flattening cylin der is adjusted so as to roll upon the spherical bodies', as they pass under the same, and flatten or broaden them out slightly. rIhe flattening cylinder is journaled in bearings 78, which are slidably mounted in brackets 79, and supported by adjusting screws 80. y

The cylinder 64, is .geared to move in unison with thebelt 63, and as shown said gearing comprises sprockets 81, 82, connected by a sprocket chain 83, a gear wheel 84, upon the shaft S5, of the sprocket 82, and .a gear 86, upon the shaft of the cylinder 64. By means of this arrangement the cylinder is moved in lunison with the belt 63, so that it rolls out the spherical bodies as they pass undereneath.

I have provided Va lubricating device for lubricating the knife, and shaping cylinder, inasmuch as the material which is used is quite sticky and might otherwise adhere to the parts. As shown, a supply tank S7, is supported over the machine, and a distributing pipe 88,leads from the tank, which pipe is controlled by ia valve 881. The pipe 88, has faucets 89, extending out from it which discharge the lubricant upon the knife and shaping cylinder 43. The flow of the lubricant 'is controlled by a rod 90, which is connected with the handles of all of the faucets, so that by moving the rod the supply can be regulated at will. l/Vater is usually employed as a lubricant although of course other suitable lubricant may be substituted therefor.

A guide roller 91, has been provided for the knife, and said roller is carried by arms 92, which are adjustably mounted upon the ears 13b. This roller bears upon the knife and aids in guiding the same in its vertical movement.

When the beater 16, is employed it is geared to some other rotating element of the machine, and as shown a simple form of gearing comprises a sprocket 93, upon the shaft of the beater, a sprocket 94, upon the shaft of the roller 42, and a sprocketchain 95, connects the sprocket wheels.

In operation the feed worms force the stock out through the discharge orifices, the knife cuts off the sections which protrude beyond the spouts, and they fall'upon the feeding roller 42, which brings them down to the channels formed by the grooves in the faces of the cylinder 43, and plate 53. The cylinder 43, rolls the bodies against the plate and forms them into spheres. They fall upon the paper covering over the conveyer belt and are intermittently advanced by the eccentric and pawl and ratchet mechanism, passing under the flattening cylinder and eventually being remo-ved by an attendant.
